Plans Evaluated
For our analysis, we chose twenty different-sized U.S. cities including many recognized as leaders in Green Infrastructure (GI). Our early efforts found that cities plan for GI in diverse types of plans, requiring that we expand our analysis to all city plans addressing ‘green infrastructure.’ Across the 20 cities we examined, we found 122 plans using the term ‘green infrastructure.’
Equity of GI in Urban Plans Benchmark
Our framework considers the equity of GI in three major ways. First, equity in GI planning requires engaging with affected communities and having clear processes for community control over how initiatives are designed, implemented, and evaluated. Secondly, the guiding visions of plans must be rooted in robust definitions of equity and serve larger goals of justice for marginalized and oppressed communities. Lastly, the multiple values of, the hazards managed by, and the labor required to realize and maintain GI must be understood in their spatial and social contexts.
